I was comparing beta 30 and the radiosity-changed exe for any differences 
when using thread count 1 or 2 and found it varies depending on scene file 
complexity or animations. I was wondering if thread count was being checked 
by others.

Getting a 160% slower render sometimes when using Work_Threads=2 versus 1, 
and other times 60% (much faster). In the past I had been making sure to 
keep the threads at only 1 so renders wouldn't slow down on larger sized 
images or animations. I think there might have been a change but couldn't be 
sure about that.

Right now it seems to be unpredictable instead of guaranteeing a speed-up by 
going with more than 1 thread. Thought maybe this hasn't been discussed 
recently so wanted to bring it up again.
